GENERAL DESCRIPTION

The UNICOMM interface modules are able to establish communication line between HART®-capable field devices and process controller computer. The communication can be done via USB or RS485 line, and also via Bluetooth®. The UNICOMM HART® modems are applicable not only for NIVELCO transmitters, but for all HART®- capable transmitters which use standard HART® communication. The device is galvanically isolated from both (USB and HART®) sides, when it is used as a HART®-USB modem, connected into the USB input of a PC, the modem does not need external power supply.
The UNICOMM SAK-305 modules can be connected into a suitable device with RS485 interface, used as a HART®-RS485 modem.
The communication protocol is HART® on the RS485 line. In this case the device needs external power supply. The Ex versions can be connected to transmitters placed in hazardous areas.
